What documents should I provide to prove my eligibility to work in Thailand as a freelancer?

Hi all! I applied from Canberra Aus on Jan 5th, I received my first correspondence for supporting docs on Jan 29th. Three times they have asked me to supply a VEVO check/status but I am Aus citizen so in the end I supplied a pdf with 2 things (a letter to them stating I’m not eligible to show status in VEVO, a copy of my Aus passport). I had previously already supplied my Aus passport (in the application initially). Then they asked for another supporting document of proof (Jan 30th) I’m able to work in Thailand by my company. I’m a freelancer and supplied this letter with my initial application. Then I submitted a reissue with a bullet point stating ‘the consultant is able to work in Thailand should she wish to’. Today I’m asked for the same thing again so I reattached the same doc (this is a letter from the HR department of my clients which I showed my primary income from).

Anyone else with similar experience? Should I be submitting a different doc/letter to support this? I’m in a fully remote contract and all my contracts states fully remote outside of AUS. 🙏
